Victron Energy Smart Battery Sense, Voltage and Temperature Sensor, Long Range (up to 10m)

Update (11/18/23): The VE app keeps historical data for 180 days, and will also generate graphs (e.g. voltage and temperature) [pics added]. Update (2/12/23): Current inventory of VE products: (2) 100V/50A, (2) 100V/30A, (1) 100V/20A, (1) SmartShunt IP67 (newer), (1) SmartShunt (older), (1) BatterySense. Best feature is the VE.Smart networking feature, which allows the components to work together to optimize charging of the battery bank. Summary: This review is for the Smart Battery Sense monitor, which is a bluetooth voltage and temperature monitoring device. This has voltage and temperature monitoring. Whereas the SmartShunt can measure current too, but lacks the temperature ( can be added with an extra sensor ). Current solar/PV system specs: 4kW of panels (most are 100W panels); 24-volt, 21kWh marine AGM battery bank; 3500W inverter; VE SmartSolar MPPT controllers: 20A (one), 30A (two), 50A (one); battery sense monitor (one). Observations: Currently have the battery monitor and two current shunts (one for battery, and one in energy monitor mode to see the current draw into the inverter). One of Victron's best features is the ability to network the controllers together, so that you don't over charge your batteries. I am running four (4) VE MPPT controllers, and 75% of the panels feed into those, but I have a few other test MPPT controllers as well, so having the capability for the VEs to stop charging (absorption and float) is very important to prevent over charging your batteries. Recommendation: If you're trying to determine if the Victron Energy family of components is worth the extra money, I would say yes, based on the ability to integrate different components (mppt, battery monitors [current, voltage]). If you have a simple system, and do not need bluetooth monitoring, there are other solar/PV controllers for less. Pros: VE iPhone/iPad app works well; VE networking. Cons: None for now. Conclusion: At $40, rating this 5-stars.

If you do not have a BMS on your battery, this works surprisingly well and even has a video on how to connect. Good value, great product so far. I got mine stuffed between two Tesla modules. I will add a picture of what you’re trying to avoid as well and why this is important to have.

Bought this because it's victron and they are the best and recommended by many DIY installers and professionals. I bought this item for it's intended use and I can say 100% that it works as intended and super easy to setup. Because it's bluetooth there can be some weird connectivity issues but I don't blame this device I blame bluetooth because of how finicky it can be on different devices. Anyway, the value for the money and the accuracy which I compare to a Craftsman multimeter from 25+ years ago and it's right on point with the volt measurements which are graphed in real time. The one thing I don't like is there seems to be either no ability to zoom into the the time window if the peaks and valleys are low and high. I couldn't find a way to narrow down when my battery went from no draw to draw. I could see the valley but I couldn't see the peak even if pinching my fingers on the screen like I would have expected to work. All good, still give this a 5 stars because it's just awesome and so is the price.

Easy to install Great price Use as stand alone or in addition to Victron "Smart" devices Bluetooth connection through app. All needed install accessories included. (Obviously not wrenches or whatever to attach the wires)

Works as it should. Connects over Bluetooth to other Victron devices perfectly.

These are the most flexible way to check your 12 to 48 volt batteries. I now have 4 sets to keep track of the electric boat, solar panels, home generator, and my motorcycle. From my chair I can review it all on one phone app. The history is useful as it covers months if reviewed occasionally. Some batteries have this, but at a bigger price. A recent upgrade shows these will always have the best data, easy to install and to find.

This device measures the ambient temperature along with battery voltage for 12, 24, 48V battery systems. The temperature sensor is internal, so you should attach this device directly to one of the battery cells. Installation is quick with only one positive and one negative lead. Configuration in VictronConnect is straight forward. Other bluetooth devices on the network will be able to utilize the values, like not charging below freezing or temperature compensation. An external temperature sensor would improve this product.

So far so good. This will give me some added peace of mind, being able to monitor my batteries temperature in the coming Idaho winter. I’d mark off half a star if I could for the Bluetooth range. It’s less than the SmartSolar controller, and I have to be within 10 feet for it to register. It’s mildly inconvenience, but not a dealbreaker. Overall very happy with it.

Victron is a quality product and easy to connect, configure and integrate into other Victron products.

Fácil instalación e integración en la red. Recomendable

C,c'est bon pour la batteries

Ben heel blij met dit betaalbaar apparaatje van Victron. Een aanvulling in de app, Bluetooth . Je krijgt net wat meer informatie.

Come tutti i prodotti victron che ho acquistato anche questo semplice rilevatore ti temperatura è ottimo si interfaccia con la rete V.E.smart di victron con gli altri apparecchi e comunicano con precisione fra di loro senza fili rendendo le letture e eventuali curve di carica ancora più precise.
